Obama, Romney hit the campaign trail Saturday

CHARLOTTE, N.C. (AP) - Both President Barack Obama and Republican Mitt Romney are embarking on a four-day march through battleground states.  Romney stops in Jacksonville while the President heads to the Gulf Coast.

With his party's faithful streaming to Charlotte, N.C., for next week's convention, Obama returns to Iowa on Saturday. For his part, Republican Mitt Romney looks to capitalize on a newly energized GOP fresh from its convention with a rally in Cincinnati before joining running mate Paul Ryan later in the day here in Jacksonville.

Both campaigns are crisscrossing the country as the campaign enters September, each day adding to the sense of urgency in a presidential contest that has remained tight since Romney sewed up the nomination in April.

As for Romney's visit it begins today at 5 p.m. at the Jacksonville Landing.  Doors open at 2:30 p.m.
